GENERAL DESCRIPTION
These EPROMs operate from a single 5V supply (in the read
mode), and therefore, are ideal for use in microprocessor-based
systems. One other 13V supply is needed for programming. All
programming signals are TTL level. These devices are programmable
using the SNAP! Pulse programming algorithm. The SNAP! Pulse
programming algorithm uses a VPP of 13V and a VCC of 6.5V for a
nominal programming time of thirteen seconds. For programming
outside the system, existing EPROM programmers can be used.
Locations can be programmed singly, in blocks, or at random.
The SMJ27C010A series are 131072 by 8-bit (1048576-bit),
ultaviolet (UV) light erasable, electrically programmable read-only
memories (EPROMs).
These devices are fabricated using power-saving CMOS
technology for high speed and simple interface with MOS and bipolar
circuits. All inputs (including program data inputs) can be driven by
Series 54 TTL circuits without the use of external pullup resistors.
Each output can drive one Series 54 TTL circuit without external
resistors.
The SMJ27C010A EPROM is offered in a ceramic dual-in-line
package (J suffix) designed for insertion in mounting-hole rows on
15.2mm (600mil) centers, and a 450 x 550 mil ceramic LCC package
(ECA suffix).
